COMBINATION ROPE SOCKET AND JAR Filed Jan. 15, 1940 12 I lnvenior Pu$S//Oran fleafr A iiorneys Patented Mar. 4, 1941 UNITED STATES PATENT OFFICE2 Claims.

The present invention relates to new and useful improvements in welldrilling devices, and more particularly to a combination rope socket andjar or jarring attachment for well drilling tools, and has for itsprimary object to provide a device of this character wherein the ropesocket and jarring tool are combined as one unit.

Another object of the invention is to provide a tool which eliminatesthe necessity of using a swivel socket and set of jars and therebyeliminate a great deal of expense of these two separate tools.

Another object of the invention is to provide a combination swivelsocket and jar which will cause the drill stem and bit to turn morefreely in the hole, thereby drilling straighter holes.

Other objects of the invention are to provide a device of theaforementioned character which will be strong and reliable in use,comparatively light in weight and which may be manufactured at low cost.1

Still other objects and advantages of the invention will become apparentfrom a study of the following detailed description, taken in connectionwith the accompanying drawing, wherein like characters of referencedesignate corresponding parts through the several views, and wherein:

Figure 1 is a vertical transverse sectional view of the device embodyingmy invention.

Figure 2 is a vertical transverse sectional view of the rope socketportion of the jar.

Figure 3 is a transverse sectional view taken substantially on the line33 of Figure 2.

Figure 4 is a transverse sectional View taken substantially on the line4--4 of Figure 1.

Referring now to the drawing, in detail, it will be seen that thereference numeral 5 designates a tube constructed of metal or othersuitable material, and provided with apertures 6, I and 8. Mounted inthe upperend portion of the tube 5 and secured therein as by welding orotherwise, as at 9, is a rope receiving plug I having a bore IItherethrough which is enlarged at the bottom end of the plug as shown inFigs. 1 and 2 of the drawing. The plug I0 further has a transverseopening I2 therein which alines with the opening 8 in the tube 5. Ashoulder is provided within the tube at the bottom end thereof which isconstructed by inserting two sections of a split ring I3 therein andwelding the same thereto as shown at I4.

A drill coupling I5 having a threaded socket I5 at its lower end portionfor engagement with a drill, is slidably engaged in the tube 5 with itsheaded portion II within the chamber I8 and secured to the socket I6 bythe shank [9. The drill coupling I5 is provided with a squareintermediate portion 20 between the shank I9 and socket IS in order thatthe socket I6 may be turned by a wrench when attaching the same to thedrill.

When the rope 2I is attached to the device one end of the rope isinserted in the bore I I and is thereafter expanded in some conventionalmanner in the lower end of the bore after which operation suitablesealing means, such as putty, is inserted through the opening 'I to sealoff the rest of the chamber I8. After the putty has been put in placemolten lead or other suitable metal is poured through the alinedopenings 8 and I2 and is allowed to harden or solidify about theexpanded end portion of the rope 2| to anchor the same within the bore II.

When the device is operated to jar a tool attached in the socket I6 thetube 5 is reciprocated to permit the lower end of the tube to contactand hammer against the shoulder 22 in one direction and against the headI? in an opposite direction. When the device is operating in this mannerany water or other fluid within the chamber I8 is permitted to escapetherefrom through the openings 6 and I. As can be seen, the head I! andshank I9 are permitted to freely rotate in the tubular member 5 and thusprovide a swivel connection between the tubular portion 5 and the drillengaging member I5.

Although I have shown and described herein a preferred embodiment of myinvention, it is to be definitely understood that I do not desire tolimit the application of the invention thereto, and any change orchanges may be made in the materials and in the structure andarrangement of the parts, within the spirit of the invention as claimed.

What is claimed is:

1. A combined socket and jar comprising an elongated perforatedcylinder, a shank having a head on its upper end slidably arranged inthe cylinder, a sectional sleeve fastened in the lower end of thecylinder and through which the shank passes, the upper end of the sleeveforming a shoulder for engagement by the head, a bored plug having alower portion fastened in the upper portion of the cylinder, the lowerend of the bore of the plug being enlarged to receive an enlarged end ofa cable passing through the bore of the plug, that part of the cylinderbetween the lower end of the plug and the upper end of the sleeveforming a chamber through which the head of the shank moves, some of theperforations forming drain openings for the chamber and the lower partof the plug having a transverse opening therein registering with aperforation in the cylinder and in communication with the enlarged partof the bore for permitting material to be introduced into the large partof the bore to hold the cable end therein.

2. A combined socket and jar comprising an elongated cylinder havingperforations therein, a shank having a head at its upper end, asectional sleeve fitting in the lower end of the cylinder andsurrounding the shank with its upper end form'- ing a shoulder forengagement by the lower end of the head, said sleeve being welded in thelower end of the cylinder, a socket member connected with the lower endof the shank and the upper part of the socket member being ofnon-circular shape in cross section to receive a Wrench, a. bored plughaving its lower part fitting in the upper part of the cylinder andwelded in the cylinder, the lower end of the bore being enlarged toreceive an enlarged end of a cable having a portion passing through thebore.
